Credit cards and credit score

[winebreeze]

Hi, I was wondering whether it is best to get rid of credit card's, closing the accounts or having a zero balance but keeping them open?
What's best to build a credit score for a mortgage? Thanks

Having available credit of £15000 but very little used, is apparently the best for your credit rating.
I didn't know this until I'd got rid of 2 credit cards, and my credit score has now gone down since I only have 1 with a £4K limit.

@SchoolNightWine thank you. I'll cut them up instead so I can't use them but keep them open

I've always been told you need a little debt to have a good score. As a pp said, you need to be seen to have credit, but not use it.

I put all my petrol on a credit card each month and pay it off in full. My score is excellent even with small cc debt, a mortgage and car loan. It's because I never miss a payment and my available credit is high.
